KL3102, KL3112, KL3122 - Dual-Channel Analog Input Terminals,-10 V to +10 V, 0/4 mA to 20 mA

KL3112, KL3122 - Introduction

Two-channel analog input terminals 0 mA...20 mA and 4 mA...20 mA

The analog input terminals process signals in the range of

KL3112: 0 mA ... 20 mA
KL3122: 4 mA ... 20 mA.

The current is digitized to a resolution of 16 bits (default: 15 bits), and is transmitted, in an electrically isolated form, to the higher-level automation device. The input channels of the Bus Terminals have differential inputs and possess a common, internal ground potential. The terminals combine two channels in a single housing. A wire breakage or overload condition are detected, and the terminal state is relayed to the controller via the K-bus. The Run LEDs indicate the data exchange with the Bus Coupler, while the Error LEDs indicate overload.
