Modular I/O boards for every simulator signal.
A SimStack – a Foundation board with Input and Output boards – connects the switches, lamps, gauges, motors and data buses in your simulator to your simulation platform. Start with a Foundation board and add exactly the input and output you need.
SimStack features
- Ethernet connectivity
- Comprehensive integration with most simulator software
- Stackable DIN-mount design for scalability and flexibility
- Up to 128 independent digital inputs per stack
- Up to 16 analogue inputs per stack
- Up to 120 independent digital outputs per stack
- All outputs provide 4096 steps of Pulse Width Modulation (PWM) control
- Support for LEDs or incandescent bulbs
- Output voltages between 0 and 32V DC and up to 3A per channel
- Outputs can be configured as common cathode or common anode (switched ground or switched supply)
- Onboard microprocessor with software updates over Ethernet
