Z-5DI-2DO is a mixed digital module with Micro USB front port of programming, 5 digital inputs (Redd, Proximity, PNP, NPN, contact) selectable via software, nr.5 totalizers @ 32bit with maximum frequency 5 kHz and settable forwards or backwards, nr.2 SPST relay outputs 2 A 250 Vac NO / NC type selectable via jumper. All totalizers are stored in non-volatile memory (FeRAM). For each input the module offers the measure of period, frequency, TON, TOFF.The module has 1.500 Vac isolation between input and remaining low voltage circuits and 3.000 Vac between outputs and the remaining low voltage circuits. The instrument stands out for its wide range operating temperature (-20 .. + 65 C) and configuration flexibility.Z-5DI-2DO supports RS485 serial communication with ModBUS RTU protocol , up to 64 nodes without repeater up to115 kbps. The power supply wiring and serial connection is facilitated through a bus that can be housed in the IEC EN 60715 guide.
