The transmitter/relay module has been specifically designed for use with the DHC-100 positioner via plug and socket installation, and is supplied with its own terminal strip. This module provides a selectable output signal of 0-20mA (4-20mA, with 0mA indicating a fault) as a current signal output, or a 0-10VDC as a voltage output signal. It also provides 3-SPST relay contact outputs that are typically used as end of travel limit switches (open and closed) and a fault indicator (loss of power, etc.). These contacts are rated for 1A@ 24 VDC / 0.5A @ 125 VAC.
