32 isolated digital inputs in QMC form factor
The TQMC601 expands the TEWS Technologies embedded I/O portfolio with a QMC module dedicated to digital signal acquisition.
The single-width module conforms to VITA 93.0 and connects to the host through a PCI Express Revision 2.1 x1 interface.
It provides 32 digital inputs galvanically isolated from the host system, supporting external signals from 15 to 60 V DC.
This makes the module suitable for monitoring and digital-state acquisition in industrial applications and embedded systems requiring electrical separation between field signals and computing electronics.
Four isolated groups of eight inputs
The 32 channels are arranged in four groups of eight inputs.
Each group uses a common input ground and is electrically isolated from the other input groups as well as from the host system.
The input circuitry also includes polarity protection, supporting integration with external field wiring.
IEC 61131-2 Type 3 inputs from 15 to 60 V
Each input supports signalling voltages from 15 to 60 V DC and provides an IEC 61131-2 Type 3 input characteristic.
Switching levels are:
- OFF below 5 V;
- ON above 11 V;
- typical input current 2.3 mA.
Interrupt generation on all 32 channels
Every input can generate an interrupt when a signal transition occurs.
Edge detection can be configured for:
- rising edge;
- falling edge;
- both edges.
This allows the host to respond to digital events without continuously polling every input channel.
Programmable input debouncing
Each channel provides programmable electronic debouncing, allowing the acquisition behaviour to be adapted to the characteristics of the incoming signal.
Maximum input response time is 150 ns, minimum input pulse width is 150 ns and the maximum input data rate is 4 Mbps.
Air- and conduction-cooled versions
Two variants are available:
- TQMC601-10R-A – air cooled;
- TQMC601-10R-H – conduction cooled.
Both versions support an operating temperature range from -40°C to +85°C and 5–95% non-condensing humidity.
The TQMC601 can also be integrated into systems addressing Defense, Aerospace & Security applications where isolated digital inputs are required in a compact mezzanine form factor.
Integrating the TQMC601 into a complete QMC system
The TQMC601 requires a compatible QMC carrier or host platform.
It can be integrated with the TPCE210 PCI Express Gen2 dual-QMC carrier or the TCPS210 3U CompactPCI Serial carrier with three QMC sites.
For wider system requirements, the TQMC601 can be integrated through ECRIN Systems’ COTS and Modified COTS approach.
Project management, production and system integration and obsolescence management can also be included according to project scope.
