General Specification
The 4 channel digital input terminals acquire the binary 24 V control signals and transmit them, in an electrically isolated form, to the higher-level automation unit. These terminals contain four channels that indicate their signal state by means of LEDs and have different input filters. The input signal of these terminals corresponds to IEC"International Electrotechnical Commission" IEC is a not-for-profit, non-governmental international standards organization that prepares and publishes International Standards for all electrical, electronic and related technologies 61131-2, type 1. Additionally, the 4-channel Bus Terminals enable the direct connection of four 2-wire sensors. Four +24 V connection points are provided.
