Product Description:

The Beckhoff KL1352 is referred to as a 2-channel micro digital input module. It belongs to the KL Analog Input Module series. It is engineered for the analysis of NAMUR sensor signals. This analog input module can identify open circuit and short circuit electrical conditions within its installation system.

The KL1352 input module permits direct connection of the NAMUR sensor in accordance with IEC 60947-5-6 safety requirements. It is rated IP20 and can be installed with a changeable position. It has two inputs and is connected via a 2-wire method. The open circuit voltage is typically 8.2 V DC. The "0" signal current is less than 1.2 mA while the "1" signal current is more than 2.1 mA. The short-circuit current is normally 8.2 mA. The short-circuit detection begins at >6.5 mA. It has a switching hysteresis of 0.2 mA for precise signal detection. It can endure humidity up to 95% with no condensation under normal operating circumstances. An input filter of 3.0 ms ensures steady signal processing. It comes with 2 slot and key connection design for side-by-side mounting. The analogue module supports up to 500 V of electrical isolation between K-bus and field potential metrics. The configuration does not require an address making installation simple. During operation it consumes around 70 mA of K-bus current It weighs only 55 g making it light and easy to handle. The operation range is from ambient (0°C) to 55°C and can be operated reliably. The storage temperature tolerance ranges between -25°C to +85°C.

The Beckhoff's KL1352 Bus Terminal offers straightforward wiring with solid and flexible conductors. The EMC immunity and emission meet the EN 61000-6-2/4 criteria. The springs are actuated with a screwdriver to make secure connections. The stripping length required varies from 8 to 10 mm.
