Signal
Isolators

These units may be used as signal repeaters or converters and provide isolation between the input and output signals. The unit can convert a wide range of signals: current to current, current to voltage, voltage to voltage, voltage to current. The dual output unit offers two isolated outputs from a single input signal.

Signal Isolator
Field
configurable

Providing cost-effective signal isolator, booster or signal converter functions, this unit has the following features:
• Total isolation for 2 & 3 wire transmitters
• Field programmable input & output ranges
• 24 V transmitter / loop supply
• Universal 85-260 VAC powered.

The input, outputs and power supply are electrically isolated from each other making these units ideal for preventing or solving erratic measurements due to earth loops.

Trip
Amplifiers

This range of instruments provides voltage free contacts which change state when the input signal passes an adjustable reference point. Single and dual point versions are available. A single pole change-over relay contact is provided for each set point. The dual version offers interlocked channel operation. Basic models provide low-cost options with set-point adjustment by multi-turn trim controls accessed through the front panel.

Programmable Triple Trip Amplifier

The B12 three-point trip amplifier specification includes: universal mains power (85 to 265 VAC) or optional 24VDC (18-36VDC), Three set-points, Four digit display of monitored variable Programmable, trip points, input source and scale, delay, hysteresis, relay action, alarm type Monitored channel status indication Scaling 0-100%, voltage, mA or custom engineering units

Simple to use yet powerful menu-driven software enables fast flexible set-up from the front panel. No adjustment of internal potentiometers, internal links or plug-in cards is necessary. This versatile unit lends itself to numerous applications including detection of high/low alarm conditions and pump control.
