This unit provides relay volt-free contacts which change
state when the input signal passes an adjustable reference set-point. The
relay may be set to operate when the signal is either higher or lower than the
set point. |

Dual Point
Trip
Amplifier |
This unit provides
relay outputs which change state when the input signals (current or voltage)
pass the points set on the front panel controls. The relays may be set to
operate when the signals are either higher or lower than the set points. Relay
outputs for each channel are in the form of a single pole change-over plus a
normally open contact. Channels may be interlocked e.g. to for use in tank
filling pump control. A transducer power supply is provided as
standard. |

Analogue
Summator /
Averager |
This unit will sum
together - or subtract - up to six voltage or current input signals. The output
signal may be current or voltage and will be proportional to the sum or
difference of the input signals. Inputs signals may represent different ranges
and be of different types (e.g. current / voltage, true or raised zero etc.).
This unit will perform an averaging function with equal input ranges. |

Low / High
Signal
Selectors |
Provides a current
or voltage outputs which are equal to the lowest (low selector) or highest
(high selector) of up to six input signals. Input signals may be current or
voltage but must be of the same type and span and must be able to share a
single common line. NB a solution to this limitation would be to isolate each
input using the 107-3A isolator. |

Comparator |
Compares two input
signals and provides a relay output which changes state when the signals differ
by an amount set by a front panel control. The relays each provide one
change-over and one normally open contact. One relay operates when input A is
greater than input B, the other when input B is greater than input A. |

Digital
Divider |
This unit provides
an output which is the frequency of the input signal divided by a user
adjustable integer. Inputs may be contact closure, change-over contacts,
voltage level change, open collector or proximity switch. The output types
include electromechanical counter, open collector, relay or voltage pulse. The
unit can provide a transducer power supply. Two versions are available.
The
two decade has a maximum division of 99. The four decade unit has a division of
9999 and further multipliers of x0.1 or x0.01 available. |

Frequency
Scaler |
This unit provides an
output which is the frequency of the input signal divided by a user adjustable
non-integer number. Inputs and outputs are as for the Digital Divider. Output
Frequency=Input Frequency × R ÷ N ÷ D where R=0.000 to
0.9999, N is any integer from 1 to 9999 and D=1, 10 or 100. |

Digital
Lineariser
|
(or function
generator) This unit will accept a voltage, current or resistance input and
provide an isolated current or voltage output which can follow any desired
pre-programmed law. An optional multiplier input enables the output to be
multiplied by an external variable. |

Pulse
Isolator |
This unit will
condition and isolate a variety of input signal types and provide a clean,
optically isolated and shaped output. Inputs may be contact closure,
change-over contacts, voltage level change, open collector or proximity switch.
The output types include electromechanical counter, open collector, relay or
voltage pulse. The unit can provide a transducer power supply. |

Pulse
Summator |
Up to five digital
(pulse) input signals may be summed to provide an output signal which equals
the sum of the input pulses. An optional version operates as an adder /
subtractor. Standard inputs (24V pulse) are optically isolated; other types of
input catered for are volt-free contacts and externally isolated TTL or CMOS
signals. Output options include open collector and electro-mechanical counter. |

Status to Analogue Converter |
Provides an analogue output which
is proportional to the number of active inputs. Each unit will accept up to
five inputs but multiple units (current output) may be connected in parallel.
The number of input signals required for full scale output is set by internal
switches. e.g. to provide a full scale output with 15 input signals present,
three Status to Analogue Converters would be required, each set for 15 inputs.
Applications include providing a
signal to a dosing pump proportional to the number of guns being operated in a
spray booth for overspray paint reclamation. |

Generator
(programmable) |
A versatile programmable
instrument which may be configured either as a Ramp Generator or a Raise Lower
device. Control of the output signal is provided by three inputs; Start/Raise,
Stop/Lower and Reset. Optional PC software provides user selection of all
functions except output signal rise and fall times which are user selectable by
internal switches (NB may be supplied preconfigured to required settings
without any user programming required). |
