RS485 (2 WIRED) to RS422/RS485 (4 WIRED) CONVERTOR

Specifications :

Model LD15UCR is "RS485 (2 wired) to RS422/RS485 (4 wired) Convertor Repeaters" which is designed for Converting RS422/RS485 from 2-wire to 4-wire and vice versa & driving signals to a longer distance. Additionally, input and output signals are isolated.

Models Available :

  • MLLD -15 UCR : RS485 (2 Wire) to RS485 (4 Wire) Convertors.



RS232 to 0-20 mA CURRENT LOOP CONVERTOR

Specifications :

It is a bi-directional converter useful to convert RS232 to 0-20 mA current loop and vice versa. Uses Tx and Rx only (DTR, DSR optional). Supports all combination of current loop i.e.

  • Active Tx - Passive Rx
  • Passive Tx - Active Rx
  • Active Tx - Active Rx
  • Passive Tx - Passive Rx

It provides upto isolation against erroneous glitches, spike suppression, fuse protection & short circuit on each current loop O/P i.e. Tx and Rx (optionally DTR, DSR)

Models Available :

  • ML LD-1 C RS232 to 0-20 mA Current Loop Convertor



R5232 REPEATER/ISOLATOR

Specifications :

It is a bi-directional converter useful to convert RS232 to 0-20 mA current loop and vice versa. Uses Tx and Rx only (DTR, DSR optional). Supports all combination of current loop i.e.

Features :

  • Supports Tx, Rx DTR, DSR with LED indication.
  • All signals are isolated and surge protected.
  • Transient protection is 2500 V peak.
  • Maximum Distance 15 metres on both sides.
  • Requires 230V AC.

Models Available :

  • ML LD-14I RS232 Isolater / Repeater



SURGE PROJECTOR

Specifications :

[Parallel / Serial (RS232C) / RS422 / RS485] Protect your parallel / RS232C / RS422C / RS485 data lines from unexpected surges and ground spikes.

  1. High surge capability : The DB25 surge protector dissipates power upto 600 watts in one milliseconds.
  2. Quick response : The protector has response time that is almost instantaneous at one Pico second. Transient surge are clamped at 6.8 V or 18 V for parallel or serial respectively.
  3. Low impedance : Once connected to the parallel / serial port, it takes minimum load to your system - about the same as a gender changer
  4. Open failure : Unlike some other surge supressors, this protector falls "open" should your system experience an extreme transient or severe current overload. Therefore if the unit fails, data & surges are shunted to ground instead of back into your equipment.

Models Available :

  • Model SPZS1 for serial R5232 2-wire Tx, Rx.
  • Model SP2S2 for serial RS232 4 wire Tx, Rx, DTR, DSR.
  • Model SPZS3 for serial RS232 7wire Tx, Rx, RTS, CTS, DTR, DSR, CD
  • Model SPZS4 for serial RS422/ RS485 4 wire i.e. +Tx, --Tx, +Rx, -Rx.
  • MLSP—2S for parallel port Centronics/Bitronics Size :60 mm X 70 mm X 12 mm
