The USB-Relay-8 is a compact USB 2.0 module in a plastic housing with 8 relay outputs for low switching capacities up to max. 1 A. A number of status LEDs visualize the switching states of the relays. The connection wiring is done via two 8 pole pluggable screw terminals.
- 8 *Relay outputs NO (36V DC / 1A / 10 W)
- Galvanic isolation between contact and coil: 1.5 kV RMS /1 min
- Timeout protection function
- LED status display per output channel
Reed relays with normally open (NO) function are used in this product. They are suitable for smaller switching capacities and achieve well over 100 million switching cycles. The electrical isolation between input and output circuit is up to 1.5kV.
Timeout-protection-function [Single channel adjustable new feature since 2020/Q4!]
If communication with the DEDITEC module is interrupted in a timeout case, the timeout protection function takes effect. It can be set for each digital output whether it is to be “switched off”, “switched on” or left unchanged. Motors can thus be switched off in a timeout case, for example, and connected horns or other alarm transmitters can be switched on.
New timeout modes [New feature since 2021/Q3!]
3 different timeout modes: “normal”, “auto reactive” and “secure outputs” for different procedures in case of a timeout event.
In “secure outputs” timeout mode, access to the outputs is blocked after a timeout event, thus preventing further access to the outputs.
Unlocking must be done by an additional software command.
Each digital input and output has a separate LED that lights up when the signal state is active. Furthermore, the status of the operating voltage, the communication with the interface, error events or the occurrence of a timeout can be displayed.
Pluggable screw terminals are used as connectors. Conductor cross-sections of up to 3.3mm² can be connected. The two flange screw connections provide additional support.
