| Item Description | The s-dias digital mixed module DM 167 has eight digital inputs (+24 V/3.7 MA/5 MS) and eight short circuit proof outputs (+24 V/1.7 A) in two groups. The power supply for each channel group is monitored for under voltage. In compliance with the safety-relevant requirements of the BG institute for occupational safety (bia), the outputs on the primary (+5 V) and the secondary (+24 V) sides are isolated using optic couplers (according to application class 3, pollution degree 2). For the inputs, the primary (+24 V) and the secondary sides (+5 V) are separated using optic couplers. In the monitoring circuits of the voltage supply for each channel group, the primary (+5) and secondary (+24) sides are also isolated with optic couplers. GND and EXTGND are not galvanically isolated (for safety reasons, not required). The clearance between conductor paths complies with UL regulations |
