Isolation amplifier TS-500, Isolation amplifier Ex ia for switching contacts
Features
- Input for switching contact, proximity switch Namur type acc. to DIN EN 60947-5-6 or opto-coupler
- Input intrinsically safe acc to: ATEX II (1) G [Ex ia] IIC/IIB ATEX II (1) D [Ex iaD]
- Switchable line fault detection for broken and shorted lines
- Output relay SPDT contact or electronic (transistor passive) available
- Supply voltage 230 V AC or 24 V DC
- Power on LED, status / error LED
- 22.5 mm case for DIN rail mounting
Isolating switch-coupler TS-500 Ex can be used for monitoring and controlling digital signals out of the hazardous area. The intrinsically safe input is suitable for switching contact, proximity switch acc. Namur DIN EN 60947-5-6), or passive electronic outputs of other devices. The devices must be installed out of the Ex-area, because only the input is intrinsically safe.
Requirements
- It is necessary to keep the conditions of the ATEX EC-Type Examination Certificate.
- The device must be installed in dry and good monitored rooms.
- If the intrinsinc safety input is connected to the dust endangered area of zone 20 or 21, it has to be ensured that the corresponding devices in this circuit have the requirements of category 1D or 2D.
- Reparing and design modifications may only be carried out by the manufacturer.
