6.5 TRLYS1B Relay Output with Coil Sensing

The Relay Output with coil sensing (TRLYS1B) terminal board holds 12 plug-in magnetic relays. The first six relay circuits
configured by jumpers for either dry, Form-C contact outputs, or to drive external solenoids. A standard 125 V dc or 115/230
V ac source, or an optional 24 V dc source with individual jumper selectable fuses and on-board suppression, can be provided
for field solenoid power. The next five relays (7-11) are unpowered isolated Form-C contacts. Output 12 is an isolated
Form-C contact, used for special applications such as ignition transformers.
