Isolating switching amplifier IM1-22EX-R, 2-channel, 2 relays NO, 20-125VDC/20-250VAC, SIL2

IM1-22EX-R is a 2-channel TURCK isolating switching amplifier with intrinsically safe input circuits and two relay outputs, each with one NO contact. Six front switches set the output mode (NO/NC) and switch wire-break and short-circuit monitoring on or off separately for each channel.

• Channels: 2 inputs for NAMUR sensors (EN 60947-5-6) or potential-free contacts
• Outputs: 2 relays, 1 NO each, 30 V DC / 250 V AC, ≤2 A, ≤500 VA / 60 W
• Supply: 20...125 V DC / 20...250 V AC (40...70 Hz)
• Housing: polycarbonate/ABS, 104 x 18 x 110 mm, DIN rail (NS35) or panel mounting
• Connection: screw terminals, 1 x 2.5 mm² / 2 x 1.5 mm²
• Environment: IP20, -25...+70 °C

Used to pass NAMUR sensor or contact signals from a hazardous area to a relay input in the control cabinet. With monitoring switched on, an input fault turns the channel LED red and the output relay drops out. Mechanical contacts need either monitoring switched off or the resistor wiring shown in the datasheet.

Approvals: ATEX, IECEx, UL, CFMUS, CSA, TR CU; for use in Zone 2. SIL 2 according to exida FMEDA.
