The 0-5 VDC corresponds to 0-100% of the selected DC output current range.
2.5.3
Remote ON/OFF
The DC output is switched on/off by a remote isolated non-powered (dry) contact connected to
the plug-
in terminals labeled “ON/OFF” (see Figure 6). A closed contact enables the power
cont
roller’s DC output; an open contact shuts it off.
A possible implementation: flow switches on the feed, product and/or reject streams of the
CEDI module or system, and an auxiliary contact of the motor starter of the RO or CEDI feed
pump could be wired in series to the coil of a time-delay relay (to allow the flow signals to
stabilize before activating). One of the relay contacts would be wired to the remote ON/OFF
input to apply DC power to the module only when there is water flow.
2.5.4
Analog Outputs
The analog outputs for the unit are listed below with associated connection information:
A selectable 0-5 VDC or 0-6 VDC output is provided for remote display of output voltage.
The signal is calibrated to 8.33 mV per DC output volt at the 0-5 VDC range or to 10 mV
per DC output volt at the 0-6 VDC range. See section 2.4.2 for configuration details.
Connect the following terminals to a remote voltmeter or display if desired (see Figure 6):
Vm+
Signal positive
Vm-
Signal negative
These signals are developed by operational amplifiers and must not be
connected to power sources or drive load resistance less than 10 K
.
A 0 to 5 VDC output is provided for remote display of output current. The signal is
calibrated to 0-5 VDC corresponding to 0-100% of the selected DC output current range.
Connect the following terminals to a remote ammeter or display if desired (see Figure 6):
Im+
Signal positive
Im-
Signal negative
These signals are developed by operational amplifiers and must not be
connected to power sources or drive load resistance less than 10 K
.
2.5.5
Output Status Relay
Output relay J8 (see Figure 6) provides a dry signal that indicates the status of the DC output:
“Enabled” (closed) or “Off” (open). This signal can be used for remote status indication (e.g.
Run/Standby status light).
Relay specifications: normally open contact, 1 Amp @ 30 VDC max.
