2 Digital Inputs, 230 VAC
Rated voltage from the supply terminal 120 / 230 VAC Nominal current from field supply ð 20 mA Nominal current from module bus ð 28 mA Power dissipation, typical ð 1 W Frequency range 47.5…63 Hz Inputs Low level signal voltage 0…20 VAC High level signal voltage 79…265 VAC Frequency range 47.5…63 Hz Low level signal current 0…1 mA High level signal current 3…10 mA Input delay < 20 ms Electrical isolation electronics for the field level Output connectivity Screw, tension spring Dimensions (W x L x H) 12.6 x 74.1 x 55.4 mm Approvals CE, cULus Ambient temperature 0…+55 °C Storage temperature -25…+85 °C Relative humidity 15…95 %, no condensation allowed Vibration test Acc. to EN 61131 Shock test Acc. to IEC 60068-2-27 Drop and topple acc. to IEC 68-2-31 and free fall to IEC 68-2-32 Electromagnetic compatibility Acc. to EN 50082-2 Protection class IP20 MTTF 1421 years acc. to SN 29500 (Ed. 99) 20 °C ■ Fieldbus and connection technology inde- pendent ■ Protection class IP20 ■ LEDs indicate status and diagnostic ■ Electronics galvanically separated from the field level via optocouplers ■ 2 digital inputs, 120/230 VAC Functional principle BL20 electronic modules are plugged into the purely passive base modules which are used for connection of field devices. Maintenance is significantly facilitated due to separation of the connection level from the module electronics. Furthermore flexibility is enhanced because the base modules provide a choice of tension spring or screw connection technology. The electronic modules are completely inde- pendent of the type of higher level field bus through the use of gateways.
