The E-opto16 may also be daisychained using the E-Out / E-In ports on other expansion boards. A wide variety of equipment that generates an output signal or voltage can be connected to each of the 2 wire dry contact inputs located on the back of the E-opto16 module. The (16) dry contact input LED status is displayed on the front panel.
The E-modules can be extended up to 300 meters from the securityProbe 5E base unit. There is no limit to how many E-modules can be connected to a single securityProbe 5E. It depends only on the number of sensors connected. A maximum of 600 data points can be monitored by the securityProbe 5E base unit.
The extra dry contact inputs on the X20 and X60 units can be switched from opto-isolated mode to non-opto isolated mode (jumper setting on the boards), where the E-Opto16 inputs are all shipped as opto isolated and cannot be configured as non-opto isolated. Because of this, the E-Opto16 inputs do require an input voltage as the module will not supply this voltage. See the E-opto16 product manual for connecting simple switches to the modules inputs.
The extra dry contact inputs on the X20/X60 units do not require any input voltage if left in their default configuration of non-opto isolated (see the sensorProbe manual for these jumper settings). The E-Opto16 (16 opto isolated dry contact inputs) expansion unit is used when the customer requires inputs of more than 5 Volts DC up to 24 Volts DC, hence the use of the term opto-isolated.
Differences between the E-Opto16 and the IO-Digital8 (8 inputs or outputs on a single sensor port) and DCS15 (single input or output on a single sensor port).
Compared to the E-opto16, the IO-Digital8 is for 5 Volts or less and it has the added advantage of supplying 5 Volts output at 20milliamps. This would be used if the inputs require 5 Volts or less or the requirements are a 5 Volt output. The DCS15 is the same only using a single input or output on a single RJ-45 port.
- The OID will start with .188.8.131.52.4.1.3854.2 for checking the sensors on the expansion modules including the E-sensor8.
- This SNMPwalk command .184.108.40.206.4.1.38220.127.116.11.1 can be used for checking all of the sensors on the securityProbe 5E.
- This SNMPwalk command .18.104.22.168.4.1.3822.214.171.124.1 can be used for returning the status of the expansion boards.
