This BS-SER module is available in versions with 8/16/32 inputs and outputs. For the digital inputs AC optocouplers are used, while the digital outputs can be selected between relay 1A, relay 3A or MOSFET 2A. The module housing consists of a stable aluminum profile with DIN rail mounting.
- Serial RS-232 interface
- 8/16/32 Digital inputs: 15V – 30V AC/DC (optional 5V – 15V)
- 8/16/32 Digital outputs: 1A, 2A or 3A
- 16 bit counter (up to 100Hz) / flipflop per channel
- Timeout protection function (configurable via software)
- Robust aluminium housing (suitable for DIN rail mounting)
With our optocoupler inputs, digital signal states can be recorded within a voltage range of 5V to 30V AC or DC. Input and output circuits are galvanically isolated from each other up to 2.5kV.
Digital In Input Filter
With our Digital-In modules, an input filter can be set in a time interval of 1ms…255ms to filter interference pulses.
This means that AC signals can also be detected cleanly.
Each input has a 16 bit counter that can count up to 65535 pulses. If the maximum counter value is exceeded, the counting process starts again from zero. By means of a software command, the current status of all input counters can be read from the module simultaneously.
Recording of status changes
Status changes that occur between the readout cycles are reliably detected by internal flip-flops and can be read out separately by software. In addition, such an event is signalled by a status LED. Resetting is done automatically after the flip-flops have been read out.
With the option “Relay outputs (1A)” reed relays with normally open (NO) function are used. They are suitable for smaller switching capacities of up to 1A and have a service life of well over 100 million switching cycles. The electrical isolation between input and output circuit is up to 1.5kV.
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
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.
With the option “Relay outputs (3A)” power relays with normally open (NO) function are used. They are suitable for switching capacities of up to 3A and have a service life of up to 10 million switching cycles. The electrical isolation between input and output circuit is up to 3kV.
With the option “Mosfet outputs (2A)” P-Ch MOSFETs are used. They are suitable for switching capacities up to 2A DC and are practically wear-free.
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.
A screwless system from the manufacturer WAGO Kontakttechnik is used as the connector. The 1-wire female connectors are 100% protected against mismating and have an eject and locking mechanism. All conductor types up to 1.5mm² can be connected.
