Digital input module DIM76001-C1 (FAPI.421459.760-01)

The module is designed to receive discrete sensor signals and contains four isolated two-wire channels of discrete input with a field supply of 24 V DC. Signal sources can be sensors of "dry contact" or "transistor key" type, connected by two-wire or one-wire scheme. When connecting the signal sources, any polarity of the field power supply can be used for each channel. All channels are isolated from the system by means of optical isolation. Input signal bounce is eliminated by software. Two channels of the module (DI1 and DI2) can be used as incremental cyclic pulse counters with a repetition rate of up to 300 Hz. The counting is carried out by the leading edge of the signal.
