ag线上真人游戏 The MTL7700 Series follows closely in the footsteps of the MTL700 but as a DIN rail mounting barrier providing quick and easy installation without the need for special hardware. Removable terminals are used for ease of installation, maintenance and for providing a loop disconnect by simply unplugging the terminals from the side of the module. Wire entry is also angled to assist wiring within limited space enclosures. MTL7700 barriers clamp simply and securely onto

MTL7700系列安全栅standard T-section DIN rail, simultaneously making a reliable IS earth connection. For applications where field power is required for switch inputs or 2-wire transmitters, the MTL7700 Series provides a bussed power feed facility. When used in conjunction with the MTL7798 power feed module the user has a fully protected, electronically fused supply to many barriers with no additional wiring required.

 

ambient temperature and humidity limits
–20 to +60°C continuous working
–40 to +80°C storage
5–95% RH
Leakage current
For ‘basic’ barriers with a working voltage of 5V or more, the
leakage current decreases by at least one decade per volt
reduction in applied voltage below the working voltage, over two
decades. For the MTL7755ac/7756ac it decreases by at least one
decade for a 0.4V reduction in applied voltage.
Terminations
Removable terminals accommodate conductors up to 2.5mm2
(13AWG). Hazardous-area terminals are identified by blue labels.
Removal force >15N
colour coding of barrier label
Grey: non-polarised
Red: positive polarity (MTL7706 negative to transmitter )
Black: negative polarity
White: dummy barrier, MTL7799
Weight

Mounting and earthing
By 35mm Top Hat DIN rail

1, the safety barrier shall be installed in a safe place, and environmental conditions can meet the general technical indicators of the requirements of the \"conditions of use\".

 

2, the isolation type safety barrier this AnDuan (blue) and the connection wire of this AnDuan circuit should be separated from laying in the hui trough, each with independent protective casing. In the side of the wiring casing is not allowed to have other power cord, including the safety circuit using the power cord.

 

3, lead to the dangerous sites should choose to have a blue this wire, copper wire line of soft area must be greater than 0.5 was.

 

4, before the isolation type safety barrier for electricity debugging, must pay attention to safety barrier isolation type model, wiring method, circuit polarity and so on, conformed to the design and the product requirements of the regulations, otherwise may cause harm to personal and equipment.

 

5, it is forbidden to use test isolation by megger insulation strength between the security gate terminal. Check system such as dielectric strength, should cut off all the connection, otherwise may cause safety barrier internal quick fuse fusing.

 

6, in the field of safety barrier programming before, must first to disconnect all wire connection and then access programmer, then live programming, otherwise may cause adverse consequences.

 

7, connected to the isolated type safety barrier of field instruments, shall be maintained through the state of explosion-proof explosion-proof test, inspection department and flame-proof certification of the instrument.

 

8, in the design, installation, use, maintenance, isolation type safety barrier, should also follow the instructions in the product manual and matters needing attention.

 

Since its introduction in 1984 the MTL700
Series barrier has established itself as the
worldwide standard for safety barriers. Known
for its quality and reliability, the MTL700
Series is widely used in applications all over
the world.
