Control Processors

The Fault connector provides a dry contact closure fault signal to notify an external control system when the PAC2 has a system fault. This output is connected to a digital input of the backup computer. A fault is defined as the CPU not interacting with Cresnet® for 10 seconds. The watchdog switches back if the backup computer is inactive for 10 seconds.

The PAC2 offers eight programmable analog and digital inputs as well as digital outputs. There are eight normally open relays, isolated with MOV suppression.

PAC2 Power Management & Requirements

When power requirements exceed 50 watts, additional power supplies may be added. For example, each keypad in the CNX-B series uses 3 watts, therefore only 15 keypads (allowing for a margin of safety) can be connected without adding an additional power supply.

To ensure sufficient power to accommodate all the Cresnet devices (keypads, touchpanels, shade/drape controllers, thermostats, sensors, and other interfaces) and to include voltage drops and wire runs, Crestron recommends the CLX-PWS75 75-watt Cresnet power supply module, or the C2N-SPWS300 300-watt system power supply.

The 75-watt power supply is designed to mount in a CAEN Automation Enclosure. A single CLX-PWS75 can

be installed in any single-width enclosure, or up to two may be installed side-by-side in a double-width enclosure. Four (4) Cresnet power ports are provided on the CLX-PWS75, which may be used to supply power directly to Cresnet devices, or connect to the external power input ports of a PAC2 or PAC2M.

If the power needed for a hub segment exceeds the power available from the internal supply (50 watts, maximum), remove the jumper from the supplied 3-pin mini connector to disconnect the internal power supply, then connect the 24VDC and ground wires from an external source (Crestron 24 VDC - regulated power supply) to the EXT and G pins.

The 300-watt power supply, specifically designed for large Cresnet control systems, operates with an input of

100 to 240 VAC, 4A (maximum) and a noise rating less than 150mV. The C2N-SPWS300 provides regulated 24 VDC, 300-watts to Cresnet system components. The C2N- SPWS300 is capable of delivering a nominal 75 watts of power at 24 volts DC on any of its eight channels.

The CLX-PWS75 is a 75 watt Cresnet Power Supply Module designed to mount in a CAEN Automation Enclosure. A single CLX-PWS75 can be installed in any single-width enclosure, or up to two may be installed side-by-side in a double-width enclosure. Four (4) Cresnet power ports are provided on the CLX-PWS75, which may be used to supply power directly to Cresnet devices, or connect to the external power input ports of a PAC2 or PAC2M.

Additional power supplies should not be mounted on CAEN-UMP plates in an enclosure that contains dimmer units because this introduces low voltage in the high voltage section of the enclosure. If required, an extra power supply, attached to a CAEN-UMP plate, can be added to a separate CAEN enclosure.
