Hardware specifications and ratings for ISOBUS Block
Technical Specifications
Power Supply
| Parameter | Specification |
|---|---|
| Input Voltage | 7-36V DC |
| Typical Systems | 12V and 24V tractor systems |
| Power Source | Through the ISOBUS connection; relay loads draw from a supply you provide |
| Power Connector | Screw terminals (BAT+, BAT-) for bench/direct feed |
Digital Inputs
The module has 8 digital inputs. Sensors and switches wired to them can drive the relay outputs automatically. See Automation (AUTO). Using them is optional: the relays are switched by hand from the VT buttons, AUX-N buttons or the web interface TEST function whether or not anything is wired to the inputs.
| Parameter | Specification |
|---|---|
| Number of Inputs | 8 (IN1–IN8 on the housing, DI1–DI8 in the UI) |
| Input Voltage Range | 5-36V |
| Input Type | Optocoupler isolated, bidirectional |
| Input Logic | Active when the input is energized; INVERT setting per input |
| Supported Signals | Dry contact (switch) or wet contact (NPN/PNP) |
| Debounce | 10 ms to 1 s per input, default 50 ms |
| Per-input timing | On delay, off delay, minimum on-time, maximum on-time |
| Input Modes | FOLLOW, TOGGLE, BLOCK |
The 32-channel module has no digital inputs.
Relay Outputs
| Parameter | Specification |
|---|---|
| Number of Outputs | 8 |
| Contact Type | 1NO + 1NC per channel (COM, NO, NC) |
| Contact Rating | 10A @ 250V AC / 10A @ 30V DC |
| Isolation | Optocoupler isolated from control circuit |

Protection Features
These protect the module and its outputs during normal operation. They are not safety functions: the module is not a safety device and must not be relied on for any safety-critical function. See our Terms of Service.
- Optocoupler isolation on inputs and outputs
- CAN bus isolation
- Automatic output shutdown on communication timeout (500ms)
- OTA update authentication
- Firmware rollback capability
- Boot failure automatic recovery
