Digital input terminals for NAMUR sensors
The EL1052 and EL1054 digital input terminal acquires signals from NAMUR field devices according to
IEC 60947‑5‑6. The sensors are supplied with a voltage of 8.2 V
DC
and return a diagnosable current signal.
In this way, a wire breakage or short-circuit can be detected in addition to the switching state. The LEDs
indicate signal or any error states, channel by channel.
