6.6.1 DC CONTROL
The ECB’s DC CONTROL section (RLY1 through RLY18) powers valves, motors, heaters, fan, etc. These devices
receive their 24 VDC power directly from the relay connector. These relay outputs power their connected devices
directly, sourcing up to 2 amps each. The (+) pin of each relay connector is hard wired to 24 VDC. The (-) pin of
each channel switches in ground via the relay. Each output channel has an adjacent LED. When an LED is on, it
indicates that the connector’s ( -) pin is pulled to ground, allowing current to flow through a connected device.
