2.5 Basic function principles
The analog input terminals
KL304x process signals in the range from 0mA to 20mA
KL305x process signals in the range from 4mA to 20mA
with 12-bit resolution (4095 steps). The terminal inputs are single-ended inputs. The KL3041, KL3042,
KL3051 and KL3052 can supply the sensors with voltage supplied via the power contacts. The KL3044 and
KL3054 have no power contacts. The power contacts can optionally be supplied via the standard supply or
via a power feed terminal with electrical isolation.
The LEDs indicate the operating state of the associated terminal channels.
• green Run LED (omitted for KL3044 and KL3054):
◦ On: Normal operation
◦ Off: Watchdog-timer overflow has occurred. If no process data are transmitted by the Bus
Coupler for 100ms, the green LEDs go out.
