The module can be used for protectionof pump against other factors than the electrical conditions, for instancedry-running. It can also be used as a stand-alone protection module.The IO 112 interface has three inputs for measured values one potentiometer forsetting of limits indicator lights indicating the• measured value of the input• value of the limit set• alarm source• pump status.96651601Electrical data:• Supply voltage: 24 VAC ±10% 50/60 Hz or 24 VDC ±10%• Supply current: Min. 2.4 A; max. 8 A• Power consumption:Max. 5 WAmbient temperature: –13 °F to+149 °F (–25 °C to +65 °C)• Enclosure class: IP 2088
