The Z-D-IN is used to interface 5 digital signals (PUSH BUTTON, LIMIT SWITCH, REMOTE, CONTROL SWITCH, RELAIS etc.) with all of control systems which are able to communicate by the protocol MODBUS RTU through the RS485 serial interface. A 16 bit counter is available on each input, the maximum frequency input is 100 Hz and it is possible to set one input as a fast counter with a maximum frequency of 10kHz. The module is ModBUS Slave and can be coupled with any ModBUS Master device. A 3-way galvanic isolation among Power supply // input // RS485 circuits assures the integrity of your datas.

Power supply: - 10..40 Vdc; 19..28 Vac (50-60 Hz)
Inputs: - 5 CH (reed, proximity, pnp, npn, contact) with common negative, self powered 24 Vdc, isolated, protected from transient up to 600 W/ms
Counters: - 4 @ 16 bit, max frequency 100 Hz; 1 @ 32 bit, max frequency 10 KHz
Anti rebounce filter: - Settable from 5 to 250 ms
Dimensions: - 17,5 x 100 x 112 [mm]
Mounting: - 35 mm guide DIN 46277
