Product Short Description
Product Name: ProSoft 1454-9F — DB9 Female to 5-Position Screw Terminal Adapter
Product Introduction:
The ProSoft 1454-9F is a passive industrial serial-port wiring adapter that converts a standard DB9 female connector into a 5-position screw terminal block. It is purpose-built for RS-485 / RS-422 field bus wiring in Modbus RTU and similar serial communication networks.
Description
Technical Specifications:
-
Brand: ProSoft Technology
-
Part Number: 1454-9F
-
Front Interface: DB9 female (9-pin, panel-mountable)
-
Rear Interface: 5-position screw terminal, 3.5 mm pitch
-
Supported Signals: RS-485, RS-422 (A/B differential pairs, GND, shield, auxiliary power)
-
Wire Gauge: 22 AWG to 14 AWG (industrial shielded twisted pair)
-
Dimensions: 50 × 50 × 25 mm
-
Weight: Approximately 50 g
-
Operating Temperature: –40 °C to +85 °C
-
Humidity: 5%–95% RH, non-condensing
-
Vibration Resistance: 5G (10–500 Hz)
-
Shock Resistance: 15G / 20 ms
-
Protection: IP30 (cabinet interior use)
-
Power Requirement: None — fully passive
-
Isolation: Not built-in; external RS-485 isolator required if galvanic isolation is needed
Functional Characteristics:
-
Eliminates DB9 crimping — multi-strand shielded cable is locked directly on the screw terminal
-
Reserved shield-ground terminal reduces communication interference from VFDs and motors
-
Protocol-transparent: passes through all serial communication without altering baud rate or protocol format
-
Compatible with ProSoft PLX31 and MVI series gateways, as well as AB, Honeywell, Yokogawa, Tricon, and HIMA communication cards
Working Principle:
The adapter provides pure physical line distribution. The DB9 female pins are hard-wired to corresponding screw terminals. When a serial signal arrives from the host device, it passes straight through the adapter to the field cable without active buffering, voltage conversion, or protocol processing.
Application Scenarios:
-
DCS/PLC Modbus RTU field instrumentation wiring (pressure transmitters, flow analyzers, variable-frequency drives, valve positioners)
-
Power plant excitation and auxiliary control system RS-485 bus termination
-
SIS safety system serial communication wiring in chemical and LNG plants
-
Retrofit of legacy RS-422 long-line communication for test instruments
Installation Requirements:
-
Fix the adapter to the cabinet wire duct or module side using the integrated mounting ears
-
Strip and insert the shielded field cable into the corresponding screw terminal
-
Ground the shield wire at the designated shield-ground terminal
-
Ensure correct A/B polarity alignment with the field device
Usage Notes:
-
No power supply or configuration is required
-
For applications demanding galvanic isolation, pair with an external RS-485 isolator
-
Keep within cabinet environment (IP30) — not for outdoor or wash-down exposure
