There are five programmable “Form A” (SPST-NO) solid state relays each rated at 500mA up to
40 VDC. These relays can be wired as NPN or PNP. The output can be set to NO or NC under
normal running conditions. If +24V is used to power the relays, the maximum current available
is 2A. This current rating is controlled by a resettable fuse (F1). Only c24V if the
voltage and current ratings are compatible with the auxiliary device being used.
NOTE: Terminals 23, 33, and 43 are DC common. Since the metal detector is grounded only
by the input power supply ground, these terminals must not be connected to earth ground by an
auxiliary device.
Out 1 (Relay K9) has one set of “Form A” (SPST-NO) contacts. It is located at terminals 24
and 26 on TB4.
Out 2 (Relay K8) has one set of “Form A” (SPST-NO) contacts. It is located at terminals 25
and 26 on TB4.
Out 3 (Relay K7) has one set of “Form A” (SPST-NO) contacts. It is located at terminals 27
and 29 on TB4.
Out 4 (Relay K6) has one set of “Form A” (SPST-NO) contacts. It is located at terminals 28
and 29 on TB4.
Out 5 (Relay K5) has one set of “Form A” (SPST-NO) contacts. It is located at terminals 30
and 31 on TB4.
Relay 1 - Relay 3 and Out 1 - Out 5 are fully programmable and may use any of four reject
timers or Overhead A-B. They can also be used as a fault or warning output. Relay 1- Relay 3
and Out 1- Out 5 are controlled using the “Reject Setup” screen which is found on the Running
Product Settings page.
RELAY NOTES
If switched power is needed for an external device in excess of the 5A 240VAC source or the 2A
24VDC source, it must be supplied from an external source using an auxiliary relay. The
voltage and ampere ratings for devices switched by the relays should not exceed the relay
ratings.
INPUTS
IN 1 – IN 8 are bi-directional opto-coupled inputs, which can be configured for several different
functions described in the following pages. Electrical requirements are listed in the
Specifications section.
NOTE: Terminals 23, 33, and 43 are DC common. Since the metal detector is grounded only
by the input power supply ground, these terminals must not be connected to earth ground by an
auxiliary device.
