|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.
