Solid-State Outputs (Type L)
The modules of the L-series (e.g., XEP01L, XSP01L) are equipped with wear-free semiconductor switches (transistors). They are particularly suitable for applications with high switching frequency (e.g., PWM, fast clocking).
Technical Data
| Parameter | Value |
|---|---|
| Type | High-Side Switch (Positive switching) |
| Switching Voltage | 12 .. 30 VDC (corresponds to supply voltage +Us) |
| Current Capacity | max. 600 mA per channel |
| Load Type | Resistive load (Inductive only with protective circuit) |
Load Power Supply (+Us)
The L-series requires a separate feed for the outputs.
| Terminal | Signal | Description |
|---|---|---|
| Us+ | Load V+ | Supply for outputs (12 .. 30 VDC) |
| Us- | Load GND | Ground for outputs |
Output Pin Assignment
The outputs switch the voltage from Us+ through to terminal Ox+. The return conductor of the load is connected to Ox- (which is internally connected to Us-).
| Bit | Terminal | Description |
|---|---|---|
| 0 | O0+ / O0- | Output Bit 0 (Return line to Us-) |
| 1 | O1+ / O1- | Output Bit 1 (Return line to Us-) |
| 2 | O2+ / O2- | Output Bit 2 (Return line to Us-) |
| 3 | O3+ / O3- | Output Bit 3 (Return line to Us-) |
| 4 | O4+ / O4- | Output Bit 4 (Return line to Us-) |
| 5 | O5+ / O5- | Output Bit 5 (Return line to Us-) |
| 6 | O6+ / O6- | Output Bit 6 (Return line to Us-) |
| 7 | O7+ / O7- | Output Bit 7 (Return line to Us-) |
Inductive Loads
When switching inductive loads (e.g., solenoid valves, contactors), high voltage spikes occur. Install freewheeling diodes directly at the load to protect the module.
