DA-600

Introduction

DA-600 detects various combustible and toxic gases discharged from industrial areas for producers, users, storage, and by-products to prevent accidents in advance.
The DA-600 converts digital signals into 4-20 mA standard current output signals and transmits them to various devices such as PLC, DDC, and recorders to establish a comprehensive gas monitoring system. In addition, DA-600 provides RS-485 communication signals and alarm relay contacts, DC 4-20 mA standard output signals realize long-range output signal transmission of up to 2500m, and RS-485 communication signal realizes long-range signal transmission of up to 1000m.
