The aluminum DIN-Rail attachment plate should already be fixed to the back panel of the EDS-505A/508A when you take it out of the box. If you need to reattach the DIN-Rail attachment plate, make sure the stiff metal spring is situated towards the top, as shown in the following figure.
Wall Mounting (optional) For some applications, you will find it convenient to mount the EDS-505A/508A on the wall, as shown in the following figures. STEP 1: Remove the aluminum DIN-Rail attachment plate from the EDS-505A/508A’s rear ⇒ panel, and then attach the...
Wiring the Relay Contact The EDS-505A/508A has two sets of relay output—relay 1 and relay 2. Each relay contact consists of two contacts of the terminal block on the EDS-505A/508A’s top panel. Refer to the next section for detailed instructions on how to connect the wires to the terminal block connector, and how to attach the terminal block connector to the terminal block receptor.
DC power source voltage is stable. Wiring the Digital Inputs The EDS-505A/508A unit has two sets of digital inputs, DI 1 and DI 2. Each DI consists of two contacts of the 6-pin terminal block connector on the EDS’s top panel.
Communication Connections EDS-508A models have 8 or 6 10/100BaseT(X) Ethernet ports, and 0 (zero) or 2 100BaseFX (SC/ST-type connector) fiber ports. EDS-505A models have 5 or 3 10/100BaseT(X) Ethernet ports, and 0 (zero) or 2 100 BaseFX (SC/ST-type connector) fiber ports 10/100BaseT(X) Ethernet Port Connection The 10/100BaseT(X) ports located on EDS’s front panel are used to connect to...
The two wires attached to the fault contacts form an open circuit when (1) a relay warning event is triggered, (2) the EDS-505A/508A is the Master of this Turbo Ring, and the Turbo Ring is broken, or (3) start-up failure.
Master and Coupler functions. NOTE If you do not enable any of the EDS-505A/508A switches to be the Ring Master, the Turbo Ring protocol will automatically choose the EDS-505A/508A with the smallest MAC address range to be the Ring Master.
EDS-505A/508A to Ethernet devices. Fiber Ports The MOXA EDS-505A/508A’s fiber ports operate at a fixed 100 Mbps speed and full-duplex mode to provide excellent performance. The fiber ports are factory-built as either multi-mode or single-mode SC/ST connectors. Therefore, you should use fiber cables that have SC/ST connectors at both ends.
