Enhance System Performance with Modicon Quantum I/O Modules

Substation I/O modules for direct 125 Vdc control
Quantum I/O modules are available for direct connection to critical 125 Vdc battery powered equipment such as circuit breakers, protective relays, transformers and capacitor banks.

  • Built-in high transient noise immunity ensures reliable operation in harsh 125 V DC environments.
  • The 125 Vdc 30A high current output module eliminates expensive high current interposing relays used in breaker tripping and closure.
  • The solid-state 125 Vdc low current output module ensures long life and trouble-free operation in higher frequency 125 Vdc switching environments without the use of expensive external snubbing circuitry.
  • Over-current/ short circuit diagnostics and protection on all solid state 125 Vdc outputs reduce downtime by ensuring quick identifi- cation of circuit prob- lems and fast repair.

Latch/Interrupt module for time critical applications
The Quantum Latch/ Interrupt module is a multi-purpose high speed input, latch,
and interrupt module combined, which is configurable through programming software. Interrupt handling instructions are part of the 984 Ladder Logic instruction set. Quantum throughput performance for 2 interrupts is typically 1ms.
High speed counters don’t miss a pulse
Quantum high speed counter modules, such as the 140EHC10500, have the ability to count pulses at speeds much faster than the Quantum controller can directly do by itself. These modules automatically report the current count to the Quantum controller every scan.

Simple ASCII exchanges
The Quantum ASCII module is a general purpose ASCII interface that provides the ability to communicate and ex- change data with devices including printers, bar code readers and scanners, weigh scales, and meters. This module is designed for relatively simple point to point ASCII communications, with ASCII messages stored inside the module triggered by logic within the Quantum controller.

TSX PLCs – Compact, Flexible, Cost-Effective

TSX PLCs
TSX Nano PLCs are easy to set up and have numerous built in functions, such as memory for storing programs, battery-backed RAM, and real-time clocks for modules with 16 and 24 I/O’s. They can be installed easily on a mounting rail or base plate in the vertical or horizontal position. TSX PLCs are programmed in lists of instructions using the FTX 117 programming terminal, in Ladder or Instruction list language using software on an FT 2000, FTX 517 terminal or PC compatible. They can be used to augment extendable TSX PLCs using a single extension per base. Depending on the model they have

16 I/O : 9 inputs + 7 outputs
24 I/O : 14 inputs +10 outputs.

The following types of inputs and outputs are used:

Inputs : 24 Volts
Outputs : Relay outputs for models with ~ 100… 240 Volt power supply, transistor outputs with positive logic for models with 24 Volt power supply.

I/O Extension

Each TSX Nano base PLC can be extended using an I/O extension. This extension is created by one of the PLCs with 10, 16, or 24 i/o. The function of each PLC is defined by the position of the coding selector switch:
Position 0 : base PLC
Position 1 : I/O extension

Peer PLCs

Up to 3 peer TSX PLCs, communicating via common words, can be connected to the base PLC. In this case, only the base PLC can receieve an I/O extension. The function of each PLC is defined by the position of the coding selector switch. I/O addressing of peer PLCs is identical to that of the base TSX PLC. The extension link cable between the base PLC and PLC extensions is shielded, twisted pair  and is no more than 200 meters long.  Each PLC has 2 reserved (IW) and 2 reserved (QW) words for exchanging data between PLCs. These exchange words are updated automatically. For each PLC, the user program is only able to write to the 2 %QW output words and read the 2 %IW input words.
