| Technical specifications |
| Output specifications |
| Number of relays | 24 |
| Relay configuration | 2 banks of 8 and 2 banks of 4 |
| Contact configuration | 24 Form C (SPDT) Normally Open, Normally Closed and Common available at screw terminals |
| Contact rating | 5 A @ 240 VAC or 28 VDC resistive |
| Contact resistance | 100 mO max (initial value) |
| Operate time | 10 ms max |
| Release time | 5 ms max |
| Vibration | 10 Hz to 55 Hz (amplitude 1.5 mm) |
| Shock | 10 G (11 ms) |
| Dielectric isolation (between relay open contact) | 300 VAC, 50/60 Hz (1 minute) |
| Dielectric isolation (between PCB output lines) | 500 VAC, 50/60 Hz (1 minute) |
| Life expectancy | 10 million mechanical operations min |
| Power on state | S2 = pull-up: Energized. NO in contact with Common
S2 = pull-down: Not energized. NC in contact to Common |
| Relay control logic polarity | User-configurable per bank via switch S1 for invert or non-invert (default). Switch settings for polarity can be read back via software through the USB bus. Switch settings do not affect the power on condition.
- Non-invert mode: When 0 is written or read back via the USB bus, relays are not energized.
- Invert mode: When 0 is written or read back via the USB bus, relays are energized
|
| Pull-up / pull-down | User-configurable per bank via switch S2 for pull-down (default) or pull-up. Switch settings can be read back via software.
- Pull-down will put the relays in non-energized mode on power up.
- Pull-up will put the relays in energized mode on power up.
