Key Features
8 parameterizable digital inputs with P-reading and an IEC 61131 type 3 input characteristic.
Rated supply voltage is 24 V DC, with a permissible range of 19.2 V to 28.8 V and reverse polarity protection.
Parameterizable delay values are 0.05 / 0.1 / 0.4 / 0.8 / 1.6 / 3.2 / 12.8 / 20 ms, each with an additional delay of 30 to 500 μs depending on line length.
Module diagnostics include sensor-supply short circuit, wire break, supply-voltage monitoring, and encoder power-supply monitoring.
Fits BU type A0. 1-wire and 2-wire connections use BU type A0; 3-wire connection uses BU type A0 with AUX terminals or a potential distributor module.
Suitable for operation on PROFINET R1 IMs; configurable with STEP 7 TIA Portal from V14.
