16 isolated digital inputs and 16 outputs in QMC form factor
The TQMC602 expands the TEWS Technologies embedded I/O portfolio with a QMC mezzanine combining digital acquisition and control functions.
The single-width module conforms to VITA 93.0 and connects to the host through a PCI Express Revision 2.1 x1 interface. A VITA 93.0 FRU EEPROM is also provided.
Its 16 inputs and 16 outputs are galvanically isolated, providing electrical separation between external I/O signals and the host system.
ECRIN Systems also presents the wider VITA 93 QMC product portfolio for applications requiring several complementary I/O functions.
16 isolated 15–60 V digital inputs
The 16 digital inputs support signalling voltages from 15 to 60 V DC and provide IEC 61131-2 Type 3 input characteristics.
OFF is defined below 5 V and ON above 11 V, with a typical input current of 2.3 mA.
The channels are organised into two groups of eight. Each group has its own isolated input ground and is electrically isolated from both the host and the other group.
Input circuitry also provides polarity protection.
Interrupt generation and programmable debouncing
Every input can generate an interrupt.
Edge detection can be configured for:
- rising edge;
- falling edge;
- both edges.
Each input also provides programmable electronic debouncing.
Maximum input response time is 150 ns, minimum pulse width is 150 ns and maximum input data rate is 4 Mbps.
16 isolated outputs with up to 0.3 A per channel
The TQMC602 provides 16 digital outputs operating from a 5 to 36 V DC supply.
Each output supports up to 0.3 A continuous current, with a maximum update time of 4 µs.
Outputs are arranged into two isolated groups of eight. Each group can be software configured for either high-side or low-side switching.
Integrated electrical protection and hardware watchdog
Output protection includes:
- short circuit;
- overcurrent;
- thermal overload;
- overvoltage up to 65 V;
- reverse polarity.
A programmable hardware watchdog automatically clears all outputs if the expected trigger is not received.
Galvanically isolated field I/O
Inputs and outputs are galvanically isolated from the host system, with additional group-to-group isolation in sets of eight.
The TQMC602 can therefore provide isolated control and monitoring I/O for industrial applications and selected Defense, Aerospace & Security applications.
Air- and conduction-cooled variants
Two versions are available:
- TQMC602-10R-A – air cooled;
- TQMC602-10R-H – conduction cooled.
Both operate from -40°C to +85°C and support 5–95% non-condensing humidity.
Integrating the TQMC602 into a complete QMC system
The TQMC602 requires a compatible QMC carrier or host platform.
The TPCE210 PCI Express dual-QMC carrier provides two QMC sites, while the TCPS210 3U CompactPCI Serial carrier provides three sites and routes QMC I/O through rear connectors P2, P3 and P4.
The TQMC602 can also be integrated through ECRIN Systems' COTS and Modified COTS approach.
Project management, production and system integration and obsolescence management can be included according to program requirements.
