  • Overview

    Isolated Input Amplifier Model 6107B
    The amplifier extends the signal range for Starloggers and Neon Remote Terminals allowing devices with low level input signals such as thermocouples and PT 100 bridges to be connected
    This Isolated input amplifier 6107B Replaces Universal amplifier 6142A and Relay Output module 6143A

    Isolated Interface Input Module Model 6141A
    This module is designed to be mounted on the 6103E Starlogger FTS and provides isolation for transducers which cannot be directly connected to a datalogger.

    Isolated Interface Input Module Model 7121A
    This module provides isolation for transducers which cannot be directly connected to the Prologger e.g. current loop transducers powered from separate supplies. Up to eight modules can be fitted to the 7100E Prologger FTS.

    4-20mA Current Loop Isolator Model 6144A
    This module isolates a Standard Starlogger 6004D-1 or Display Starlogger 6004D-2 from a 4-20mA current loop input signal. The signal is optically coupled, then converted to a voltage signal suitable for measurement by the logger. The module is partially powered by the loop current, allowing for a low power drain from the logger.

    4-20mA Current Loop Isolator Model 7121C
    This module isolates a Prologger 7001D-1 from a 4-20mA current loop input signal. The signal is optically coupled, then converted to a voltage signal suitable for measurement by the logger. The module is partially powered by the loop current, allowing for a low power drain from the logger.

    4-Channel Relay Control Module Model 6525B
    The 4-Channel Relay Control Module is an interface designed to allow the datalogger to control four magnetically latched relays. This permits the Logger to be used as a controller of four external devices through the four potential free contacts. Up to four modules can be connected to a Standard Starlogger 6004D-1, Display Starlogger 6004D-2 and Prologger 7001D-1.

    Single Channel Relay Control Module Model 6114A
    This module is used to switch on/off an external instrument from the logger, for example, switch on a pump or a lamp, or set off an alarm. It is mounted on a FTS and uses the pulse output from the logger to latch the relay. To control more devices, consider the Model 6525B 4-Channel Relay Control Module.

    Universal Counter Module Model 6118B
    The Universal Counter Module extends the number of available counter channels of the datalogger. The standard operation mode is set as four 8-bit counters. Alternatively, two 16-bit counters may be configured for use with a Standard Starlogger 6004D-1, Display Starlogger 6004D-2 and Prologger 7001D-1. Cascading of up to eight modules is possible.
