Relays
The IB1005 + SB1005 have 6 mechanical relays. These relays are rated for
30VDC/16A or 250VAC/15A. If your load is inductive in nature, then the actual
power the relays can handle may be several times lower.
Relay outputs
Relay outputs are on terminal blocks 3 and 4. Both normally closed and normally
opened lines are provided for each relay.
For terminal block 3:

Relay control
Six lines of the EM1000 (located on the NB10x0 network board) control the relays.
On power up, all EM1000 lines are configured as inputs and pulled up internally,
keeping relays off. To turn the relay on, set the corresponding control line LOW.
Naturally, each relay line must be configured as output.
For all relay control lines:
HIGH (our input*) - relay off
LOW - relay on
