Migrating From Matrox 4Sight Gpm To Matrox 4Sight Ev6; Connecting Devices To The Auxiliary Output Signals - Matrox 4Sight EV6 Installation And Hardware Reference

Migrating from Matrox 4Sight GPm to Matrox 4Sight EV6

Matrox 4Sight EV6 was designed to easily migrate devices already connected to a
Matrox 4Sight GPm. The connections and signal names are the same between
these two products; however, the following considerations should be made when
migrating devices:
• Matrox 4Sight EV6 does not support TTL devices; therefore, TTL devices
previously wired to Matrox 4Sight GPm cannot be migrated. Connecting TTL
devices to your Matrox 4Sight EV6 unit could damage the device and unit.
• The auxiliary input signals of this product are meant to be used with a reference
voltage of 24 V. Using a lower voltage power supply might provide unreliable
detection of on and off states. For the auxiliary output signals, using a reference
voltage below 24V might also cause issues if the voltage drop across the output is
such that the connected device cannot detect an on state. When interfacing the
output with a Type-2 or Type-3 digital input, an on state requires a voltage of at
least 11 V across the input, whereas interfacing with a Type-1 digital input requires
a voltage of at least 15 V across the input.
• Each individual auxiliary I/O signal on Matrox 4Sight EV6 is electrically isolated;
therefore, there is no common reference to ground. When connecting I/O, be
sure that each negative pin (-) is individually referenced to the ground of the power
supply.
• 2-wire proximity sensors are supported, but will require a 2.2 KOhm bleeder
resistor to be installed across the input terminals (the + and - pin). You must use
at least a 250 mW rated resistor for this purpose.

Connecting devices to the auxiliary output signals

Matrox 4Sight EV6 auxiliary output signals can be interfaced with input modules
(with sourcing or sinking input signals) found on most programmable logic
controllers (PLCs) and other devices. The auxiliary output signals can also be
interfaced with inductive load devices (such as a relay or a small motor).
The Matrox 4Sight EV6 auxiliary output signals are based on an NPN-type
transistor. They need to be connected to an external power source or a sourcing
device because on their own, they are not capable of providing voltage to drive a
device. When an auxiliary output signal is on, the circuit between its AUX_OUT+
and AUX_OUT- pins is closed, allowing current to flow from the AUX_OUT+
pin to the AUX_OUT- pin, if the AUX_OUT+ pin is attached to a power source
