GE IC655ALG516 Series Five 8-Channel Analog Input Module

IC655ALG516 provides eight analog input channels for a Series Five PLC. The module converts selected field voltage or current signals to 12-bit data; channel scanning and field wiring must match the installed application.

IC655ALG516 accepts 1–5 V, 0–10 V, −10 to +10 V and 4–20 mA. Configure the module range jumpers and data interpretation as described in GFK-0123A; the signal range is not determined by a software label alone.

IC655ALG516 uses 12-bit binary conversion. Jumpers select a 10 ms or 100 ms conversion interval; typical sample time also includes one PLC scan, so acquisition timing must be considered in the control program.

IC655ALG516 draws up to 250 mA from the base unit at +5 VDC and requires a separate user-supplied 24 VDC ±10% source, rated for up to 150 mA for this module.

IC655ALG516 occupies 32 consecutive input points beginning at its assigned slot reference. The documented data format carries the converted channel data and status; use the manual mapping when decoding values in the PLC program.

IC655ALG516 supports differential, single-ended or current devices. Use the appropriate terminal connections and preferably shielded twisted-pair cable; unused inputs and signal commons must be handled as specified in the module wiring instructions.
