Digital outputs
|
Type |
4 Form C solid state outputs (I/O option B & C) 1 Form A solid state output (I/O option C only) |
|
Wire |
1.3 to 0.13 mm2 (16 to 26 AWG) |
|
Max load voltage |
130 V AC / 200 V DC |
|
Max load current |
100 mA |
|
ON Resistance |
30 ohms typical, 50 ohms maximum |
|
OFF Resistance |
400 Mohms minimum |
|
Isolation |
2000 V rms, 60 Hz for 1 minute (to ground). 1000 V rms, 60 Hz for 1 minute (between outputs) |
|
Rated impulse voltage |
2500 V peak (to ground) 1500 V peak (between inputs or outputs) (CAT II) |
|
Update Rate |
20 ms (accuracy = +/- 7 ms), not including communication lag time. State changes occur within 20 ms. 1/2 cycle for internal I/O |
|
Signal Type |
Continuous or pulse |
|
Fusing |
Protect with 100 mA slow-blow fuse (such as Littlefuse 201 Series 100 mA fuse) |
|
Max output transition |
50 per second |
|
Min Pulse Width |
1 ms |
|
Timing resolution |
1/2 cycle or 1 s |
|
Transient suppression device for digital outputs |
Install according to diagrams in the section, “Digital outputs”. The customer-supplied transient suppression device must meet these specifications: Polarization = Bidirectional. Breakdown voltage = 300 V maximum. Peak power dissipation = 10 kw for 10 microseconds (minimum), and 1.5 kW for 1 millisecond (minimum). |
|
State change latency |
20 ms (Digital output) 40 ms (Digital input modules) |
|
Control schemes |
Use intermediate mechanisms so relay control can be disabled for servicing. |
