Description:

• Ex-supply isolator for standard DC current signals, a two-channel, transparent HART supply isolator with an external power supply of 22.5 mm in width.
• It can be used to transmit and isolate standard signals ranging from 4 to 20 mA from Ex Zones 0, 1, and 2 to the safe zones.
• The input to the component is both active and passive.
• More than 15 VDC can be given to external sensors.
• There are two ways to run the 4...20 mA output circuit: passively and strongly.
• Through a relay contact, status and error messages can be obtained (NO).
• The component can be set up with the help of common FDT and DTM software.
• Extra housing for mounting on TS35 rails.
• Dimensions: screw connection; nominal cross-section: 2.5 mm2; L/W/H: 119.2/ 22.5/ 113.6.
• IP 20 is the protection level.
• Sensor supply input 4...20 mA > 15 V DC.
• Passive output: 4...20 mA active 26 V DC maximum current loop of 4...20 mA
• Load less than 600 Ohm
• Precision: <0.1% v.E.
• Coefficient of temperature: <0.01% v.E./°C (Tu)
• Relay for alarm output 1: No communication Safe zone: 250 V AC/30 V DC @ 2A Zone: 32 V DC @ 1 A/32 V AC @ 0.5 A 2 Voltage differential of 19–31.2 V DC
• Loss of power of about 1.8 W
• Range of ambient temperature: -20 °C to +60 °C
• cULus, ATEX, IECEX, FM ATEX marking II 3 G ExnA nC IIC T4 ATEX characteristic data; Secure isolation EN 61010, 3-way isolation up to 2.6 kV AC/DC of all circuits against each other; Working voltage: 300 V AC/DC at overvoltage category II and pollution degree 2; approvals: I0 = 93 mA DC, P0 = 650 mW, and U0 = 28 V DC.
