The Model SIB-V245 / V453 Mixed I/O Interface Board is an external interface product which extends the ranges of the Motorola™ ACE3600 Mixed I/O module's Discrete Inputs (DI), Discrete Outputs (DO) and Bipolar Analog Inputs (AI).
- 16 Discrete (DI) inputs can be separately set to monitor 10 to 30VAC / VDC or 120VAC.
- 4 Discrete outputs (DO) are Form C (SPDT) pluggable relays.
- 4 Bipolar Analog Inputs (AI) provides test points which allow monitoring each of the four AI current signal inputs without breaking the current loop. Transient surge arrestors on the AI input can be replaced in the field with a small screwdriver.
