Johnson Controls 8872 Temperature Slave Stage Module, Dual Scale, -30-130 Degree F Temperature Range

TEMPERATURE SLAVE STAGE MODULE; RANGE -30 TO 130 F

The 8872 Temperature Slave Stage Module is a thermoelectric device that contains two optimally configured thermoelectric stages, which can be connected to an appropriate load to provide a controlled temperature output. These modules are designed for use in the HVAC industry for maintaining steady temperatures in data centers, hospitals, factory floors and other temperature sensitive environments where ambient temperatures fluctuate widely throughout the day.

The 8872 Temperature Slave Stage Module is a dual-scale temperature sensor that provides a TTL output. It measures the temperature with an accuracy of ±1.0 °F (±0.5 °C) from -30 to 130 °F (-34 to 54 °C). The slave stage module can be connected directly to any digital input channel of a Johnson Controls building automation system.

The Johnson Controls Temperature Slave Stage Module allows a load controller (such as our Johnson Controls 8871 Load Controller) to be directly connected to a stage control device, such as a high-temperature limit switch. This slave module is configured with a dual-scale, -30 to 130 degree F temperature range and provides an isolated, voltage-free output contact that can be used to monitor temperatures and activate stage control devices.

The 8872 is a slave stage module that provides temperature signal outputs at two output ranges. The slave stage module is used with the master stage modules (8870 and 8873) to control condensing units, chillers, and heat pump systems in residential and light commercial applications.

The Johnson Controls 8872 Temperature Slave Stage Module, Dual Scale provides the ultimate in accuracy and durability for laboratory temperatures.

The 8872 Temperature Slave Stage Module is a solid state, dual-scale temperature sensor designed to provide accurate information and simplify system design. The module has a negative temperature coefficient (NTC) thermistor that measures -30 to 130 degrees F (-34 to 54 degrees C) and is designed for use in HVAC applications. It features a dual-range wire-wound resistor that measures 0 to 10 volts and 0 to 5 volts with a full scale offset at 25 degrees F (0 degrees C). A K-type thermocouple input is also available.

The 8872 is a slave stage module that provides temperature control to other devices. It offers a -30 to 130 degree F temperature range, and can maintain temperatures as low as -20 degrees F below ambient. The device features Johnson Controls’ patented Temperature Proportional Control technology, which controls the output of heating elements to provide even heat distribution and fast response time.

The 8872 is a slave stage module that can be used in place of the 8800 stage module. It is intended for use with the Microtherm line of sensors. The slave stage module is made up of 4 parts: 1-slave controller, 2-variable resistors and 2-test points. The slave stage module contains temperature control circuitry that switches power to the variable resistors as a function of temperature.

The 8872 Temperature Slave Stage Module has a dual scale, -30-130 Degrees F. The 8872 is a Johnson Controls temperature sensor module designed for HVAC use.

MetroPac is a temperature control manufacturer who supplies Johnson Controls with temperature slave stage modules (part number 8872); they are used in a variety of applications, including air conditioning and refrigeration.
