DESCRIPTION
The Horner APG High Density Thermocouple Input Module offers superior channel density, with 16 input
channels per module. This module allows thermocouple temperature sensors to be directly connected to
the PLC without external signal processing (transducers, transmitters, etc.). All analog and digital
processing of the thermocouple signal is performed on the module. Temperature resolution is 0.5°C, and
temperature values may be reported to the PLC %AI I/O table in 0.5°C or 0.5°F increments. This module
features open circuit detection, where the %AI register goes to its maximum value upon an open circuit
condition, and a corresponding %I bit is energized. Field wiring is connected to a special high density, 32
position removable terminal block.
Recommended wire size is 24 AWG.
