IM1-12EX-T
EX switching amplifier universal current, with ATEX certification
Together with a Namur sensor for using the
electronic v-belt monitor in the EX area, zone 2.
Single-channel version. Intrinsically safe
control circuit with wire breakage and
short-circuit monitoring. In case of error, all
outputs are switched off. The EX switching
amplifier with transistor output is
interconnected between the Namur sensor and the
electronic V-belt monitor. LED with two colors to
visualize the switching state (yellow) and the
fault (red). Green LED to indicate the operating
state. Supply voltage: 20 – 250 V AC/20 – 125 V
DC (40 – 70 Hz) Power consumption: < 3 W
switching voltage: < 30 VDC switching current: <
50 mA Protection class: IP 20 Dimensions: 18 x
104 x 110 mm (W x H x D) Areas of application:
[Exia] IIC/IIB and Ex nA nC [nL] IIC/IIB T4.
Ex-certification in accordance with Conf.
certificate: TÜV 04 ATEX 2553
