Analog signal isolator 1-channel IM31-12EX-I The 1-channel analog signal isolator IM31-12EX-I is designed to transmit normalized active voltage or current signals galvanically isolated from the Ex area to the non-Ex area. The signal is duplicated and provided at both outputs. ■ ATEX, IECEx, UL, FM , TR CU, NEPSI C US ■ Installation in zone 2 ■ Transmission of normalized analog signals from the Ex area to the non-Ex area ■ Input circuit: 0/2…10 V or 0/4…20 mA ■ Output circuit: 2 x 0/4 0…20 mA ■ Complete galvanic isolation A green LED indicates operational readiness. Edition • 2015-10-24T21:49:51+02:00 The device features two input circuits of 0/2… 10 V or 0/4…20 mA as well as two short-circuit proof output circuits of 0/4…20 mA. The transmission characteristic is adjusted via a DIP switch on the front. In switch position 1:1 the input signal is transmitted without interference and made available at the outputs in the non-Ex area. In "LZ" switch position, a dead-zero signal at the input (0…10 V / 0… 20 mA) is converted and provided as a livezero signal at the output (4…20 mA). 1/4 Hans Turck GmbH & Co.KG ñ D-45472 Mülheim an der Ruhr ñ Witzlebenstraße 7 ñ Tel. 0208 4952-0 ñ Fax 0208 4952-264 ñ [email protected] ñ www.turck.com Analog signal isolator 1-channel IM31-12EX-I IM31-12EX-I 7506321 Nominal voltage Operating voltage Frequency Operating voltage range Power consumption Universal voltage supply unit 20…250 VAC 40…70 Hz 20…125 VDC ð 2.2 W Voltage input Input resistance (voltage) Current input Input resistance (current) 0/2…10 VDC ï 50 kò 0/4…20 mA ð 50 ò Output circuits Output current Load resistance, current output 0/4...20 mA ð 0.5 kò Rise time (10-90%) Dropout time (90…10%) Measuring accuracy Reference temperature Temperature drift ð 50 ms ð 50 ms ð 0.1 % of full scale 23 °C ð 0.005 % / K Galvanic isolation Test voltage 2.5 kV Important note Ex approval acc. to conformity certificate Application area ignition protection category Max. values: Max. output voltage Uo Max. output current Io Max. output power Po Characteristic Internal inductance/capacitance Li/Ci External inductance/capacitance Lo/Co Edition • 2015-10-24T21:49:51+02:00 Dimensions Type code Ident no.
